Gisele Bundchen is effortlessly stylish in skinny jeans and a leather jacket as she runs errands in New York

She is one of the most successful models in the world and it's not surprising when Gisele Bundchen can look this good in casual clothing.

The 33-year-old beauty looked runway ready as she stepped out in New York in skinny jeans and a leather jacket.

Bundchen doesn't need heels to elongate her already long legs and opted for a pair of flat black boots on her casual day out.

A bright scarf and sunglasses completed the look and she pulled her hair back in a messy bun.

The Brazilian supermodel recently recorded a sexy dance remake of Blondie's disco hit Heart of Glass for H&M's summer campaign.

Now, following this promising start, Gisele is singing a new tune - a British rock'n'roll classic at that - for the Swedish brand's autumn campaign, with proceeds from the sale of it on iTunes going to help give better lives to disadvantaged children around the world via UNICEF.

Gisele's version of All Of The Night by The Kinks will be available for free download from hm.com and will also be on iTunes, raising money for UNICEF.

For every single download from iTunes, H&M will make a donation to UNICEF to enable the purchase of vaccines for children.

'I am so excited to be the face of H&M this autumn,' the supermodel exclaimed. 'I love the street style look and that we can raise funds for a good cause. I hope everyone downloads my song.'

Fans of the supermodel can also catch a one minute preview of Gisele singing the song in the studio in her husky, sexy Brazilian accent where she also manages to pronounce the word 'you' as 'chew'.

At the end of the session, Gisele appears to be turning into a wild animal as she yelps into the microphone and adlibs for the studio engineers and producers.

After then taking off her headphones, Gisele gives a shake of her supermodel locks and with a big broad smile tells the studio guys: 'You see? Yay!'

The H&M campaign will debut on September 12.
